To all tuimm it mag concern v it known that I, GUs'rAvE O. DEGENER, citizen of the United States, residing in New York city,- in the county of New York and State of New York, have invented certain new and useful Improvements in Gomhined Type-Whiting, and Computing Machines, of which the following is a specification.

This invention relates to combined typewrit 1g and computing machines, and more especially to means for coupling" the traveling element or carriage of the computing mechanism so as to move concommitantly w'th the carriage of the typewriting mecha- ....um, and so that a computing head much shorter than the typewriter carriage can be used, without the necessity of having the cemputing mechanism connected to the type it-er carriage during the entire run of the coupler is provided between the mov- 'llliSDl and the carriage of the' typewriemg niechanlsm, whereby the carriage can pick up the computing element at any ll'StlQlQl'llllIlGLl point, enabling the computn mechanism to be"brought in play at any t in the typewritten line, giving a range variable positions which is valuable for use on a long carriage, the use of very'long iii shafts, etc, for the computing mech- Ltllmlil being rendered unhecessary.

The improvement is shown in connection with a computing mechanism of the type in which a master \wheel isgiizen a rotation of variable extent at each actuation of a numeral l ey, depending on the particular key actuated. This movement is transmitted successively to a series ofcomputing wheels with which the master wheel is. brought m coijperation step by step by the movement of the typewriter carriage. For this purpose the typewriter carriage is provided with one o more pick-ups or couplers any one of I rich may bearranged soas to engage a A lock normally holds the omputingcariae'e stationary, but is amonatically reer traveling element-of the computing leased. The computing carriage disengages itself from the coupler onthe return movement of the typewriter carriage.

@ther features and advantages will hereinafter appear.

Referring to the drawings, Figure 1 i a side view in elevation, with parts omitted for the'sake of simplicity and with parts broken away to show the underlying struc ture. Fig. 2 is a fragmentary front view in elevation, with parts broken away to disclose the elements lying beneath the same, and showing the lock disconnected from the end plate of the machine, and with one of the p1ck-ups in engagement with the catch carrying the movable element ofthe computing mechanism along with-the carriage.

Fig. 3 is a view similar to Fig. l, showing the lock secured to the end plate of the machine holding the movable element of the computing mechanism stationary and all of the pickups disconnected from'the' catch. Fig' i is a view similar to 'Figs. 2 and 3,

.showingone of the pick-ups in engagement with the catch, either in the act of picking up the movable element of the computing mechanism, or in the act of being disengaged from the movable element of the computing mechanism. Fig. 5 is a fragmentary perspective view showing the parts in the position illustrated in Fig. 2. Fig. 6 is an enlarged fragmentary vertical section showing one of the pick-ups adjusted by its control to a position in which it will not engage with the catch, and thus be incapable of connecting the movable element of the computing mechanism with the carriage. Fig. '4' is a fragmentary side view in elevation, show ing the parts in the position illustrated in Fig. 6. .Fig. 8 is a fragmentary perspective view of one of the pick-ups, showing parts in section to disclose the structure of the control for regulatingthe active and inactive position of the latch of the pick up. Fig.

9 is a fra mentar )QlS ectiveview of the catch on the movable element of the computinggnechanism. Figs. 10 and 11 are detail views, showing the connection of the lock with the catch. V,

The invention is shown as adapted to an Underwood VVright- ,combined computing and typewriting machine. Numeral keys 1 act through sub-leversflto throw typebars lhe vement the carriage may be controlled in the usual. manner by means of cscapement pawis 13 and 1%, which engage an cscapeinent wheel connected to the pinion. 10. and which are tip'ifil'atl by a 1111iversal bar 1c lyi.

in the path oi the typears 'ihe return of the escapenient pawls l3 and 1% and tile universal bar 16 is obtained in the usual manner by a member 17 normally nessed in one direction by means of a spring 153.

i The compu mechanism. indicated at is of a t; in which a member 20, which may be crmed the master wheel given a priuleterinined amount of rotation at each actuation of a innneral key which amou -t depends on the oarticular numeral key sti wit. The mas wheel 20 is provided \viih teeth which project outwardly, so as to engage between. cooperating teeth 21 which form internal gears 'lhe gears 22 are arranged in a series side by side, and are also provided with external teeth 23 so as to form external gears, which mesh with corresponding gears :24: provided upon computinc. or numeral wheelsQf). in this instance master wheel 20 is shown remaining while theorising, indicated. at- 26,

the gearsfiz and the comput- 1 I I carried along with the car-- "ag as to bring the master wheel 20 successively into c'ooperatio1'1 with each of the gears .59. The casing or czirriage 2G is provided with wheels 27 which run on a trad :28. and the carriage is further supported by means of a rod or t 'ackwhich extends through suitablebearings provided in the casing or carriage 26.

in order to obtain the desired movement of the carriage (1 which with the parts carried thereby, forms the traveling element of the computing n1cc1anism, there are provided on the arriage 5 one or .iore picl" ups 30. in this instance two are shown, but the number is not limited. Each of; these pick-ups may be of a construction suitable to engage a catch 31 provided on the computing carriage 2b. and may comprise a bracket 32 secured to the carriage 5 and provided at its trout cud with a latci1 or couplcr 33 pivotaliy mounted at 234- on the bracket 3:2.

The latch 3 is normally pressed downwardly by :1 spring 35. so as to be in position to engage the catch 31. The latter has a beveled or inclined surface i upon which the latch 31- rides during the letwrd'eeding movement of the carriage, so that the latch can drop into a notched seat 41 provided in the catch 311 thereby auto111atically coupling the carriages.

hen the latch drops into said seat ll the spring 35 :lorces it downward to an ex tent to release a lock l)- which normally holds the computing carriage 26 stationary,

so as to permit the typewriter carriage 5 to' carry the computii'ig carriage 20 alon The lock may be pivoted at l3 upon the catch 31, and is provided at one end with-a hook 4A, which is adapted to engage in an opening provided in one of the end plates ill of the machine, so as to engage on the rear side thereof, as indi :ated in Fi (3,, to lock the computing carriage 26 in its initial or normal position. The lock 4-2 may be provided with a projection or enlargement $7, to occupy normally a position in register with the notched seat ll, but standing higher than said seat, in position to be en gaged and depressed by coupler or latch 33. The lock i2 may be pressed up against a stop pin {8, by a spiral returning spring l9, arranged in socket in catch 31.

The master wheel 20 is given a rotation at the-stroke of each numeral key lto an extent corresponding to the particular 1111- meral key struck. It is necessary that this rotation shall be imparted successively to the individual gears 0r disks 22 as the successive numerals are struck. Hence the movement of the computing carriage can proceed concomitantly with the movement of the typewriter carriage, which spaces automatically at the striking of each 1111- meral key. The pick-ups 30 may be so set that the computing carriage will be auto matically picked up at the instant of striking a numeral key for the purpose of computing.

As the pick-up or coupler approaches the catch 31, it will ride up along the bevel +0, and then drop into notch 41-1, the spring 371 acting on the catch ,.3& also to depress the lock -12 sufficiently .to permit the lock or hook 44 to disengage from the opening 4.3.

Then the typewriter carriage 5 will carry along the carriage 26, by means of the coupler or catch 31, step by step, so that the master wheel 20 is brought successivclyiuto cooperation with the several computing gears or disks 22, and thus will. operate successively tllOSQVOl'H] computing wheels 25 each to an extent corresponding to the particular,numeral key struck.

The lower part of the opening l5.i1-: slightly beveled at its entrance side. Fig. (3. so that when the lock 42 enters the opening 45 at the end of the return motion of the carriage, it will be automatically cannned up into the position shown in Fig. 4. so as to rai.-1- the latch 13 to the position indicated in Fig. l. and in tact. to such an extent that lll] a further movement of the carriage xuili automatically force the latch 33 out the SQLQZJ- il. The right-hand edge of the notch 41 is cut away, as indicated at 51, for this purpose. The movement of the carriage 5 causes the latch 33 to ride on the cut-away 01' beveled corner 51 of the catch 31, so that it Will automatically be disengaged from connection With the movable element otthe computing. mechanism The lock 42-inch then rise to its fullest extent under the influence of the spring 49 to the pcsition inelicated in Fig. 6,. Whete' it Will positively lock or anchor the computing carriage in its tial position; the plate 46 serving to prevent further movement of the computing carriage, and and that the m8 returned 11013 ewritei' ca i'i'iage oveinent of the completed While ns stationary this structure is 1 very 'a icle typel. and in which it e chive shafts for the nia stei wheel anism employed riage toward the right. It Will thus be seen machine, That that the lock 42forms a positioner for tle- 0nd in length termining the initial location of the comput ing carriage, and also forms a clisconnectci' for disconnecting the latch 33 from the catch 81.

The opposite corner of the notched seat ll need not he cut away to the same extent. so that when the latch 33 comes in engagem t .With the catch 31 it will be securely connected to the catch 31 and carry the co-mputing carriage along" With'it. o and 1 It may be desirable to throw one or more nism which of the pick-ups 30 outof operation. If such l fright is the case, a cast-ofi' device 36 may he operated to raise thefront end of the latch to such aheight that it Will be incapable e1"? properly engaging the catch 31 This clevice' is shown in the form of a pin 37 rotatably: mounted in the bracket 32 and providedwith a finger .38 to engagea tail 39 "provided on the latch 33 so. as to depress said 'tail 39-and raise the front encl of he latch 33. The position ofthelatch anaicast of? device in the inactive condition of pick-up is shown in Fig. 7. It Willhe seen from-this 'viewthat the end of the' h'ger i q at length in the r and the mechh would have I of the main machine; all 01": By using the oi moderate o; the master tying mecha- Underwoodout, however, limiting since a line perhaps iches long can be Written head 26.

Thus it will be seen that thecomputin stationary 'riage, and they see on the carriage he worksheet,

The distance between the columns on the Work-sheet may be greatly in excess of the distance or in tervals between said zones on the computing head. Thus, in this and other Ways, it Will be seen that the device is of advantage in en cabling computations to be performed by a compact computing device, in the several Zones thereof, although the numbers so computed may be disposed at very great inter-' vals across a Wide work-sheet. The distance between the adding zone on the computer may be only one-half an inch or less, While the distance between the corresponding columns on the Work-sheet may be eight or ten inches. This makes a relatively short'addotherwise need an adding carriage of the same length as 'the typewriter carriage. Upon returning the typewriter carriage to begin a-neW line, theaddilig carriage will become automatically disconnected there from, and the type-Writer carriage will com plete its return movement, While the computing carriage remains'stationaryariations may be resorted to Within the scope of the invention, and portions of the improvements may be used Without others.
